Specification forming par-t oiLetteis Patent No. 150,143, dated April28, 1874; application iiled July 21, 1873.

To all whom it may concern Be it known that I, WILLIAM FAY, of the cityof New Orleans, parish of Orleans, State of Louisiana, have made certainnew and useful Improvements in an Automatic Fan ;A and I hereby declarethe following to be a full clear,

and correct description of the same, reference being had to theaccompanying drawing making a part of this specification.

My present invention relates to an improvement upon my automatic fan.for which Letters Patent of the United States were granted to me the25th day of March, 1873, said patent being numbered 137 ,189. 'lhepresent invention, like my former patent, consists substantially of amechanical combination and arrangement of a toothed-wheel gearingoperated-by spring-power, through which rotary motion is imparted to aflywheel, from which, by mea-ns of cranks and connecting-rod,reciprocating motion is transmitted to a rock shaft, in which may beinserted, at any desired angle, one or more fans of the kind in generaluse for fanning or cooling purposes; but it differs in other respects,and in some essential particulars, from my said patented invention, asis hereinafter described. My present invention, like my former onereferred to, isequally effectual for the purposes for which it isdesigned in almost any relative position in which the same may beplaced, by simply adjusting the fans on the rock-shaft before mentioned;and by turning' the device upon, or by raising and lowering the same bymeans of, the ad- `instable telescopic pedestal shaft or spindle towhich the same is secured, its eects may with the greatest facility bedirected to the face of the person upon whom the. same is desired tooperate. In this respect consists the novelty, utility, and main featureof my invention, the construction and operation of which, and theparticulars wherein it differs from the said patented invention, will bemore clearly understood by reference to the accompanying drawing.

Figure 1 is a front elevation of the device complete and ready for use,with a single ilywheel and a single fan or set of fans; while Fig. 2 isa rear elevation of the same, showing likewise an additional fly-wheelupon the opposite end of the fly-wheel shaft, with an additionall fan,rock-shaft, &c. Fig. 3 shows the mechanical arrangement of the springsand toothed-wheel gearing, by means of which motion is imparted to thefly-wheel and fans therewith connected.

My apparatus, as at present constructed, is operated by eight volutesprings, A, the inner ends of which are secured to the four shafts a.,there beingtwo of the said springs A upon each of the said shafts c; andthe said shafts a are, moreover, provided each with one of the fourdriving-wheels B. The springs therewith connected are wound up by meansof a crank or key applied to the ends of the said shafts a, as shown inthe elevation, Fig. 2. The outer extremities of the said springs areattached to the connecting-bars of the frame C. D and D' are stationaryshafts, provided with the pinions E and E' and wheels F and F', whichrevolve loosely thereon, the pinion E and wheel F, as well as the pinionE' and F', being cast, respectively, in one piece. Each of the saidpinions E and E' is engaged by two of the said driving-wheels B, wherebymotion is transmitted to the iiy-wheel shaft L through the said Wheels FF', the pinion G, wheel G', pinion H, wheel H', and, finally, to thewheel K upon the iiy-wheel shaft L.

My saidpatented invention has but two springs, and does not possess theeiiiciency of my improvement, wherein the combined power of eightsprings is concentrated upon the flywheel shaft L, so as to move thesame and the ily-wheel I thereon placed continuously in one direction.

Upon the side of the said iy-wheel I, and at any suitable distance fromits central axle, I place the crank-pin M, to receive one end of theconnecting-rod N. rIhis connecting-rod has its opposite end connectedwith one end of the crank-lever O, which, in turn, has its opposite endinserted in the rock-shaft P, having bearings in the brackets It,projecting from the frame S. One end of this frame is clamped to theWooden casing by which the motive mechanism of my device is surrounded,and from the casing the said frame S can be coilveniently detached. Bythe revolution of the said ily-wheel I an oscillating motion is impartedto the said rock-shaft P, through the connecting-rod N and crank-lever Oaforesaid. `In the said rock-shaft P, through perforations therein made,may be inserted at any required angle the stem or handle of one or morefans, T, to be employed by my apparatus. In my present device Iuse nobalanceweight, as in my former one 5 but, instead, I place a secondfly-wheel, U, upon the opposite endof the said y-wheel shaft L, fromwhich, by a connecting rod or wire, V, motion may be imparted to anotherfan or set of fans placed upon the device iu a room above or at anydista-nee from the machine, as required. The said second y-wheel U, withconnectingrod, rock-shaft, fans, Src., is plainly shown in Fig. 2 of thedrawing. The whole apparatus above described rests upon and is securedto the upright standard W of the pedestal-base X. The said standard W isin two pieces, both of which are tubular. The upper member, upon whichthe device immediately rests, and to which it is secured by theset-screw d, is made to slide freely within the lower tube, and may bekept at any desired elevation therein by means of set-screw e. Forregulating the speed of the fly-wheel, and the machinery therewithconnected, or bringing the same to a full stop, a friction-brake may beapplied thereto, -as shown at Y, Fig. l.

It is obvious that either a less or a greater number of springs mightbe'employed for the operation of my device, and to this end I reservethe privilege of employing one or more, as in my former patent beforementioned.

The machinery for the operation of the iiywheel is incased in a neatbox, and the whole device is cheap, simple, and eflicient for thepurposes for which it is designed; and

Having described it, what I claim as new, and desire to secure byLetters Patent, is-

The operating clock mechanism herein described, in combination with arock-shaft having a series of perfor-ations, a, fau T, and secondaryflywheel U, the whole being constructed and arranged substantially asdescribed, whereby the fan may be adjusted to any required angle uponsuch rock-shaft, and the whole device xed upon the tubular pedestal W atany required height by means of the setscrews.

VILLIAM FAY.
